Abstract
The temporal coherence function |Γ(τ)| of picosecond pulses from a Nd: YAG laser has been measured by diffraction at a transient grating. The coherence timet c =7 ps is small compared to the pulse widtht p =22 ps but is in correspondence with the spectral bandwidth Δv=12·1010 Hz. The new method for measuring the coherence function |Γ(τ)| is discussed and compared with a previous experiment.
